This User’s Guide uses numbers shown above to identify 

watch hands and indicators.

1.  Hold down C for about two seconds to enter the Timekeeping Mode, and 

then observe the movement of the x Second Hand.

Use the procedure under “To configure Home City settings” to configure your Home 

City and daylight saving time settings.

Important!
World Time settings depend on correct Home City, time, and date settings in the 

Timekeeping Mode. Make sure these settings are configured correctly.

See “Configuring Current Time and Date Settings”.

The face of the watch is a solar cell that generates power from light. The generated 

power charges a built-in rechargeable battery, which powers watch operations. The 

watch charges whenever it is exposed to light.

Whenever you are not 

wearing the watch, be sure 

to leave it in a location 

where it is exposed to light.

 Best charging 

 

•

performance is achieved 

by exposing the watch to 

light that is as strong as 

possible.

When wearing the watch, 

makes sure that its face is 

not blocked from light by the 

sleeve of your clothing.

 The watch may enter a 

 

•

sleep state if its face is 

blocked by your sleeve 

even only partially.

 Keep the watch in an area normally exposed to bright light when storing it for long 

 

•

periods. This helps to ensure that power does not run down.
 Storing the watch for long periods in an area where there is no light or wearing it in 

 

•

such a way that it is blocked from exposure to light can cause power to run down. 

Make sure that the watch is exposed to bright light whenever possible.

You can get an idea of the watch’s power level by 

observing the movement of the x 

Second Hand in the 

Timekeeping Mode.

 If the 

 

•

x

 Second Hand is moving normally at one-second 

intervals, power is at Level 1.
 If the 

 

•

x

 Second Hand is moving at two-second intervals, 

power is at Level 2, which is quite low. Expose the watch 

to light as soon as possible so it can charge.

 Hour Hand and c Minute Hand stopped 

at 12 o’clock.

All functions disabled.

 When power drops to Level 3, all functions will be disabled but the watch will 

 

•

continue to keep time internally for about one week. If you recharge the battery 

sufficiently during this period, the analog hands will move automatically to the 

correct setting and regular timekeeping will resume. After one week, all settings 

(including timekeeping) will be cleared. Recharging the battery will reset all settings 

to their initial factory defaults.

Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation 

temporarily whenever power suddenly drops below a certain level due to overuse 

of the alarm tone over a short period. Note that all operations are disabled while the 

watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal 

operation after power recovers (in about 15 minutes). Putting the watch in a location 

where it is exposed to light will help power to recover sooner.

Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a 

certain period in an area where it is dark. The table below shows how watch functions 

are affected by Power Saving.

 There actually are two sleep state levels: “second hand sleep” and “function sleep”.
